2 SHEEIS-SHEET '1.

The levers 23 are each formed in two parts 24 and 25. The parts 24 and 25 are in al inement when in a normal operative pos tlon and all of the parts of said levers are pivottion'as shown in Fig. 2, so that onthe depression of one of the keys 22 the inner end of the part 25 of the two-part lever on which the key is mounted will be forced u Wardly. Each lever 23 is restored from a epressed position to its normal operative position by a spring 29, one end of which is secured to the base 13 and the other end passed through an aperture in the key lever part 25. The shoulders 27 and 28 and the mountings of the arts 24 and 25 provide a knee or knuckle oint which adapt all of the parts 24 of all of the'key-operated Levers to fold relativelyto the parts 25 as shown in dotted lines in Fig. 1.

The inner ends of the parts 25 of the keyoperated levers 23 have a pin 30 and each pin is adapted to move in a slot 31 of an arm 32. The arm 32 forms a part of the bellcrank lever 33' and each bell-crank lever is pivotally held in a bracket 34 extending upwardly from the base 13 or to a common ivot rod. as preferred. The arm 35 of each ell-crank lever 33 is pivotally held by a knee or other joint at its outer end 36 to an upwardly extending link 37, and said link 37 at its upper end is pivoted at 39 to the short arm 40 of a type-bar 41. .Each typebar 41 is adapted to have a plurality of type or characters thereon according to whether a single case shift or double case shift is employed. The type-bars are adapted to rest at their forward ends-upon a felt, rubber or other cushion 42 and arearranged'in a curved path within the type basket 43, said type asketi being. suitably held in the main frame part of the machine in such a way that when a key-operatedleverris moved on the depression of a key, the actuation ofits coiiperating bell-crank-lever 33 will force a link 37 'downw'ardly and this will'cause one of the type-bars to move the type upwardly and rearward-1y to make an impression upon the work sheet aboutthe platen 44 in the usual X3 a means to lock the keys and the foldable parts of the key-operatedi' levers to fold and unfold together, a bar 45 extends trans versely of the machine over the parts 24 and under the parts 24 is a shaped .rod 46. The rod 46 is pivotally mounted between the sides of the shallow frame part 15 and is adapted to be forced to the position shown in dotted linesin Fig. 1 so that the transversely extending portion 47 will lie directly under the parts 24 of the key-operated levers thus holding the parts 24 of said levers which fold between the transversely extending bar 45 and the portion 47 and thereby prevent their disarrangement. The bar 45 may have a rubber or other strip forming an engaging surface for the key-operated levers, and the rod 46 may have a knob or handle to move the same 1t being understood that the key-lever parts 24 are not held so tight between the bars 46 and 47 as will prevent such relative movement of the keyboard frame part 15 and the key-lever parts 24 as is necessary because of their different pivot points. If desired the pivots of the levers and the keyboard frame part may have a. common axis or pivot rod or shaft.

The platen 44 is mounted carriage 48. This platen carriage 48 is adapted to travel transversely of the mashine on a foldablesupport. This su has two members 50 and 51 which are hlnged substantially U- together at 52 at the upper portion of the machine. The support member 50 rests when in a normal operative position upon 0.

upon a platen pport transversely extending bar 53 forming .a part of the vertically movable member 50 of the platen carriage support. The platen carrlage may be variously constructed. As shown it comprises end pieces or brackets 54 which extend upwardly from a carriage base 55 and said base may be held to travel transversely of a carriage bed. The carrlage bed may extend rearward as far as the hinge 52 or may be supported between foldable arms or in any other desiredway. The carriage end pieces 54 support the axis or shaft 56 of the platen and said end pieces may also support a paper apron 57 in which may be mounted a pressure or feed-roll 58,

there being paper fingers and such othe parts'as are usually employed to holdan-d guide the work about the. platen. The member 51.of' the platen carriage carrying the platen and its supports may be turned rearwardly anddownwardly on the hinge 52 to place ducethe height of the machine. This position of the platen and its support is illustrated by dotted lines in' Fig; 1. Y

While the drawings show a particular form of folda'ble platen carriage, escapement and ribbon mechanisms, and case shift mechanism, such features form no part of the present invention and for that reason further illustration or dpscription was not the platen directlyunder the bar 53 and within the main frame to thereby re-- thought necessary as these features are covered in' other pending applications filed b me March 4, 1916, Serial No. 82,138; arch 6, 1916, Serial No. 82,406; March 6, 1916, Serial No. 852,407.
